| Research Abstract |
We have established a formation method of excess electron in ionic liquid using photo-ionization, and shed a light on the reaction dynamics and kinetics of solvated electron with several different solutes. The spectra of solvated electrons in ionic liquids are located in near infrared region. It has been found that there is a strong Coulombic screening effect on the ionic reactions in ionic liquids. Using twin-pulse laser excitation method, reaction dynamics of excited-state radical in ionic liquids has been precisely examined.
